IMPROVEMENT IN CAR-COUPLINGS.

Specification forming part of Letters Patent No. 166,537, dated August 10,- 1875; application filed July 3,1875.

To all whom it may concern:

Be it known that I, JOHN M. MARLIN, of W illett, Indiana county, Pennsylvania, have invented a new and Improved Oar-Coupling, of which the following is a specification:

Figure 1 represents a top view, partly in horizontal section, of my improved car-coupling; and Fig. 2, a vertical transverse section of the same, on the line a; m, Fig. 1.

Similar letters of reference indicate corresponding parts.

My invention relates to an improved automatic car-coupling, which is simple in its construction and reliable in its operation; and it consists of pivoted and spring-acted side bars, that are guided by rigid top and bottom draw-head bars, to retain on their flanged and concaved front ends the coupling-pin, until they are forced apart by the entering link, for dropping the link for coupling. The link is V wider at the central part, to prevent its enterretain the side bars in position, and secure their binding on the coupling-link F, for holding it in position for coupling. The side bars have flanged and grooved or concaved jaws B at their front ends, which nearly touch each other at their upper and lower points, and serve to retain thereby the pin G in position in the top hole of the upper draw-head bar A, until, by separating the side bars by the link, the pin is released and dropped for coupling.

The central portion of the link F is made wider to prevent it from entering too far into the draw-head, and it gives, also, in connection with the spring side bars, a flexible coupling, that yields to the vibrating motion of the link as imparted by the cars.

The coupling of the draw-head is readily accomplished by the entering of the link, which is held by the jaws of the approaching draw-head, and guided by the receiving side bars, even when striking them at varying angles. I

Having thus described my invention, Iclaim as new and desire to secure by Letters Patent An automatic car-coupling composed of stationary top and bottom guide-bars, pivoted and spring-connected side bars, with grooved front jaws, with coupling-pin resting thereon, and of a centrally -widening link, all con-V structed substantially as specified.
